He wore a sleeveless shirt with a skull on it, and resembled his father, except that he had yellow teeth and yellow eyes.
In 1992, Biff Jr. was apparently 11 years old, the same age and in the same grade of school as Verne Brown; and as much of a bully as his father had been. In one instance, he stole an arrowhead from Verne and then based a presentation on it for his class, raising his grade to a D+, while causing trouble for Verne. As a result, Verne, who had been planning to show the arrowhead to the class, decided to go back in time to obtain something more interesting, and stole a dinosaur egg.
Behind the scenes
- The existence of Biff Tannen, Jr., was postulated in a draft screenplay for Part II, and Back to the Future Part II established that Biff had a grandson in 2015. Biff's son was introduced as a character in Bravelord and the Demon Monstrux, and identified as Biff, Jr., in Verne Hatches an Egg, the last episode of Back to the Future: The Animated Series.
- In both episodes, child actor Benji Gregory is listed in the voice cast. Gregory, better known for his role on the science fiction comedy series ALF between 1986 and 1990, was 14 years old at the time of filming, and appears to have been the voice of Biff, Jr.
